In our lab, we have implemented a simple Julia wrapper to Qhull in order to compute Delaunay triangulations in arbitrary dimensions.
We interface with Qhull via ccall (instead of PyCall ), so you don’t need to install scipy in your system, just Qhull itself and a C compiler. Moreover, we are using the re-entrant version of Qhull. Thus, our wrapper should be thread-safe (even though we have not confirmed it).
Hope you find the project useful!
